I have just purchased a new bike and would like to run a dual ring with bash guard up front for all the obvious reasons. The bike has a brand new Ltd edition Raceface crank (Ano red sexy) up front, is it possible to adapt/convert this or is it a brand new component?
Anything else that will need changing front mech sounds obvious?
Thanks for your help.
you should just need to replace the big ring with a bash ring, unless it's some hippy-dippy funny bolt pattern, but I doubt it is.
if you think the 32T middle ring is going to be too low geared, you can swap that for a 36T then get a bigger bash, but up to you.
Just replace the big ring with a bashring. That's it.
Thanks fellas. But surely the front mech will need adjusting etc?
Anyone recommend a decent bash ring?
You should only need to adjust the stop screws on the mech to stop it over shifting.
In theory yes, you can drop it a bit but if you're sticking with a triple front mech then since the middle/granny rings aren't moving it should need moving.
I found a double specific mech helped massively on my 2x9 setup but I don't have a bashring so the chain tended to fall off towards the outside which a bashring would have stopped.
I have a bashring to sell - 32T 4-bolt size in black. Used but not trashed. It's a truvativ one IIRC - £10 posted (email me if you want it)
Raceface make some nice ones, look on CRC
1) Change your middle ring from 32 to 36 or you will be way undergeared
2) Fit a 36 bashring in place of your big ring
3) Move your front mech down as far as possible and set the stop screw so it won't move beyond the middle ring
S'easy
Cheers El capitano! Bish... bash... bosh. Done.
Thanks for the offer on the ring Clubber, i'm gonna hit CRC tho. 
This could be dangerous
further more....
what are chain guides/devices for and would they be compatible with the above set sup?
Defo going 36t.
Chain devices just stop your chain jumping off - I think you can only use them on a single front set up. Completely unnecessary unless you are a downhill racer
the captain is talking poo.
plenty of dual ring devices, some BB mounted some iscg mounted
I must admit... i did assume that they are for SS use only?
no, most are single ring but E.13 do a double ring one, some others may also.
I do agree with the captain about the DH racer though. I have 22/36/bash on my evil and ride it just as hard as I can. I have never had a dropped chain. I've a suspicion that they (chainguides) come into their own when dealing with rear sus setups where the cainline and mech is being bashed around all over the place.
Sound, thanks for that. For the limited ammount of DH i participate in it would be overkill.
for the limited amount of DH that gets done, forks over 100mm, tyres over 1.9, rear suspension, big wide riser bars, short stems........ are probably overkill too.
pros: keeps the chain on when it gets rough
cons: weight, increased friction on chain
apparently you are changing to double and bash for all the obvious reasons!
I say that it's down to preference, and what you are comfortable with to be honest.
The freedom of choice is a wonderful thing!
As it happens... my shoulders are of a 'barn door' type width and i find that my 710mm Easton fits me bang on... if that's o.k with you?
The bash ring is due to my increasing confidence, genuine neglect of the big ring and combination of more technically demanding riding where i feel that it will be of benefit. Phew.
shoulda just stuck with
"...would like to run dual and bash....."
its your bike, build it how you want, then ride it where you want.
having said that your bars are far too wide - fix it and report back please
Any how...
Already got a xc/trail bike set up in the conventional manner.
I should have all the boxes ticked then.

Exactly why I went from triple to double and bash. Never regretted it
thanks to everyone that was constructive... the 36t is bang on.
had the bike round Dalby at the weekend and didn't miss the old set up at all!

My Heckler came with a 3-ring RaceFace Atlas crank set, added a RF bash ring onto it pretty much straight away. As stated above, I didn't need to move the front mech position, just adjusted the limit screws.
I've a suspicion that they (chainguides) come into their own when dealing with rear sus setups where the cainline and mech is being bashed around all over the place.
Certainly in my case. I was dropping the chain on nearly every descent, despite using a medium-cage rear mech and keeping the chain as tight as possible. I added a Blackspire Stinger and haven't looked back since.
